Abstract
A method for operating a latch and a latch circuit are disclosed. The latch circuit comprises a storage sub-circuit, a propagation sub-circuit, and a shared clock-enabled transistor. The storage sub-circuit is configured to capture a level of an input signal when a clock signal transitions from first level to a second level and hold the captured level to generate an output signal while the clock signal is at the second level. The propagation sub-circuit is configured to enable a path through a blocking transistor to the shared clock-enabled supply node to propagate the captured level of the input signal to the storage sub-circuit. The shared clock-enabled transistor is configured to couple the shared clock-enabled supply node to a power supply while the clock signal is at the first level and decouple the shared clock-enabled supply node from the power supply while the clock signal is at the second level.
